Following the instructions here...
During an upgrade from 1.0.3+b2850 to 2.0.0+b2990
Ran the following commands...
$ cd /opt/redash/current
$ sudo bin/upgrade
After the ugprade command ran, restarted both the supervisor and the entire server, and when it starts up, the configured data source no longer shows up in the list. Logging into pgsql directly, I can see the entry in the data_sources table, however it does not show up in the data sources. Rolling back to 1.0.3 by changing the symlink brings the data source back.
I did see this error in the supervisor log while trying to look into this..
